TRACTION ATTACHMENT FOR AUTOMOBILE-WHEELS.

To all whom it may concern.' 5

Be it known that I', GEORGEADAMS, a citizenof the UnitedStates, and a resident of St. Louis, Missouri, have invented certain nw tachments for Automobile-Wheels, of which `the followingis a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates traction attachments for automobile-wheels; and it consists of the novel features'herein shown, described, and claimed.

In the drawings, Figure 1 is anelevation of a wheel having a solid-rubber tire and my improved traction attachment applied to the Fig. 1 and Fig. 3 is an edge view ofthe wheel Shown in Fig. 1. Fig. 4 is a cross-section through the rim of and taken on the line 4 4. Fig. '5 is a cross-section through the rim of the wheel shownin Fig. J2 and taken on the line 5 5. Fig. 'is a cross-section upon the line- 6 6 of F1 2. Fig. 7 is a longitudinal section upon t e line 7 7 of Fig. 6. A

` Referring to the drawings in detail, the flat band 8 is-wlde enough and long enough to cover the periphery of the hat rubber tire 9', the ends o theband being turned up to form the ears 10 and 11 and the draw-bolt 12 is inserted through the ears to tighten the band upon the tire. v Flanges 13 extend from theV edges of the band 8 engage the sides of the tire and hold the band in position. Teeth 14 have Shanks 15 inserted throng lthe band 8 and riveted. In the -modiiiedconstruction the band 8 is curved in cross-section to fit the curvature of the pneumatic tire 16. The teeth 14 and the band 8 produce a roughhod wheel which will engage -the roadway and prevent rotary slip-- ping ofthe wheel and also side slipping. y t0 improvements in M rough-shod' wheels are intended principa ly for use as driving-Wheels for heavilyloaded automobiles and Wagons and the like.

I claim- Y In a traction attachment for automobilewheels, the combination with a tire, of an encircling band constructed of a single Strip of material fitted to the tread of the tire and having integral portions that extend downwardly Onto the sides of the tire, teeth riveted tO the encircling band and projecting Outwardly therefrom, a pair of perforated lugsl integral with the meeting ends of the env circling band, and a draw-bolt passing through atsuitable intervals to 35- the perforated lugs; substantially as specified.

In testimony whereof I have Signed my 1 name to this specification in presence of two subscribing Witnesses.

GEORGE ADAMS.
